MARTIN SHIRK, OF EPHRATA, PENNSYLVANIA.

TOBACCO-GRANULATING MACHINE.

SPECIFICATION forming part of Letters Patent No. 308,101, dated November18, 1884.

Application filed October 22, 1883. (No model.)

T0 ZZZ whom it' may concern.-

Be it known that I, MARTIN SHIRK, a citizen of the United States,residing at Fphrata, iu the county of Lancaster, State of Pennsylvania,have invented certain Improvements in Tobacco-Granulating Machines, ofwhich the following is a speciiication.

My invention relates to improvements in tobacco granulating or scrappingmachines and the objects of my improvements are, first, to cut thetobacco into scraps, and, second, to separate the different sizes oftobacco cut, the one from the other.

I illustrate my device by means of the accompanying drawings, which formpart of this specification, in which similar letters refer to like partsthroughout the several views.

Figure I is a view of the side of the machine on which the power isapplied; Fig. 2, a view of the reverse side. Fig. 3 is a top view withthe hopper removed. Fig. 4 is a top View of the hopper. Fig. 5 is avertical section through line x x, Fig. 3. Fig. -6 is a perspective viewof the concave breaker-bed and the horizontal cylinder, and Fig. 7 is aperspective view of the relative positions ofthe screens E and F.

In these two last views there has only been enough of the receiving-boxshown to explain the movements of the internal parts.

In my device the tobacco is fed into a hopper, A, resting upon the topof the receivingbox B of the machine. The hopper feeds into a concavebreaker-bed, C, the whole bottom of which is formed of a coarse sieve,S, with a mesh that will allow particles of the required size to passthrough, from the upper part of the inner side of which projectwrought-iron or steel teeth t, set in two horizontal rows, the one abovethe other, and so arranged that the teeth of one row are set oppositethe center of the openings between the teeth of the other row. Ahorizontal cylinder, D, on the shaft s fits in the said breaker-bed, andis revolved by the cog-gearing g g', having the crank a attached, theshaft being supplied'at the end opposite the gearing with a ily-wheel,w. This cylinder D has two sets of teeth, r, about its circumference,which, as thecylinder revolves, pass between those of the bed. Theseteeth are square, having theirfacets perpendicular and horizontal, sothat when they engage the respective facets of the one set shall beparallel with those of the other set. rIhe bottom of the hopper Ahas anopening, A', in it, covered with a sieve of .the same mesh as thatforming the bottom of the breaker-bed. The cog-Wheel gis mounted on apin, z, secured in the side of the receiving-box B. It is so mounted inorder to avoid passing an additional shaft through the receiving-box.Below the breaker-bed there is a screen, E, having a finer mesh thanthat of the breaker, which moves alternately back and forthlongitudinally in the machine, the delivering end c of which projectsback of the receiving-box. Under E there is a still iiner sieve, F,suspended at right angles to it, and. having a movement perpendicular toit. Screen E is suspended by two arms, b, inside the receivingbox behindand one, d, outside in front, and

screen F by arms f at one side and hat the other.'

Motion is communicated to the screen E by means of a cam, c, attached tothe-shaft s between the receiving-box and the fly-Wheel, and the leverI, having its fulcrum at Z, one end of which is curved, so as to embracethe cam, and the other bent at right angles, so as to enter thereceiving-box through the circular slot ,where it is connected with thesieve. The sieve F is moved by a lever, m, having two horizontal arms atright angles with each other-one, a, attached to the sieve E through aslot in the receiving-box, and the other, a, secured to the sieve F. Thevertical part p of the lever, passing through a covered slot in thecross-piece q of the frame supporting the receiving-box, serves as afulcrum for the arms. As will be seen, by this arrangement theoscillating movement of the arm attached to the sieve E in one directioncauses a movement of a similar kind of the other arm in the otherdirection. The sieves are sloped so as to cause them to graduallydischarge their contents E to the back of the machine, and F into areceiving-box, It, having a sliding bottom, o, and a movable top, o. Abox, H, is placed beneath the sieve F to receive such tobacco-dust aspasses through it. riDhe hopper can be removed from the top of thereceivingbox when necessary.

In using my device the tobacco'is put into the hopper, when suchparticles as are small .IOO

What I claim as my invention, and desire to secure by Letters Patent,is-

1. A concave breaker-bed, C, having a sievebottom, and teeth projectingfrom the upper edge of said bottom, in combination with the cog-gearinggg', shaftlS, with cylinder D, having teeth, the cam c, lever I, andsieve E, as herein described.

2. The fixed concave breaker-bed having a sieve-bottom, combined withthe suspended sieves E and F, arranged to deliver at right angles toeach other, and oscillated by levers I and m, respectively, with theactuating mechanism and the horizontal cylinder D, as herein more fullydescribed.
